Online order payment issues

On 10 July I saw that 3800 had been deducted from my credit card by Woolworths online. I immediately contacted them as the amount did not correspond with any order I had placed. After numerous calls, (I kept having to follow up myself as the call centre agents did not phone me back and I received no response to my emails) I was finally told the amount deducted was for my order placed on 25 MAY! I was extremely unhappy as the website states "payment will be deducted between 7 and 14 days after delivery". There was no communication to inform me there was a delay or a system issue (which is the formal feedback received). I reported the issue to the Ombudsman for goods and services (who in turn have forwarded the matter to the ombudsman for credit) as if I had not had any funds in my account at the time of the deduction it would have been rejected and I would have been blacklisted! The call centre agent proceeded to tell me that contrary to what their website states, they have up to 6 months to deduct payment! But the issue does not stop there, as part of my complaint I asked that they advise of any other surprise deductions I should expect.....and true as Bob there is an outstanding payment due for my February order!!!!! I received an email apologising for the issues that are due to an IT problem and was advised that my February payment would be waved as a result. Well that is not the end of their online systems issues because yesterday I received an email profusely apologising as I had incorrectly been charged twice for an online order that I placed this week using my Woolworths store card! No where on my statement or the app does this error show, I just see that all of a sudden my card balance amount does not make sense. This is beyond just an IT error now, how many other consumers have been affected by this without knowing! Check your all Woolworths online transactions
